In experimental games, as in natural situations, people are often observed acting to the benefit of others even at considerable cost to themselves. Such behavior is contrary to the assumption of selfish behavior, but it is not necessarily contrary to the assumption of rationality: People cooperating under these circumstances could be ‘rational altruists’ who base their decision on the magnitude of the external benefit, as well as on the costs to themselves. We test that proposition using a prisoners' dilemma experimental paradigm. If it is correct, we should observe higher levels of cooperation as the external benefit in such games increases. But we do not — whether external benefit is measured in terms of number of individuals benefiting from a cooperative choice or the total dollar benefit produced. Cooperation must be explained otherwise. 相似文献

The objective of this article is to provide an analytical framework for addressing the sources of great power regional involvement and its effects on regional conflicts. The thesis of the article is that variations in the degree of intensity of conflicts and the likelihood of successful conflict resolution in different regions are affected by the character of great power involvement in these regions. Our argument is that although great power involvement or noninvolvement cannot cause or terminate regional conflicts, it can either intensify existing local conflicts or mitigate them. We will propose causal linkages between balances of great power capabilities and interests, types of great power involvement in regional conflicts, and patterns of regional conflicts. The study will distinguish among four types of great power involvement in regional conflicts: competition, cooperation, dominance, and disengagement. The empirical section will examine the application of these propositions in seven historical illustrations, representing the four patterns of great power involvement in regional conflicts. All the illustrations will deal with one conflict-ridden region-Eastern Europe and the Balkans, in successive historical periods from the post-Napoleonic era to the post-Cold War era. Because of the variety of patterns of great power involvement in Eastern Europe and the Balkans, this region is uniquely suited to examine the propositions derived from the theoretical framework. Drawing on both the theoretical deductions and the historical illustrations should make it possible in the last section to discuss briefly the implications of the proposed framework for regional conflict management or mitigation in the Balkans in the post-Cold War era. 相似文献

Immunofixation procedures were used for detecting alpha-1 antitrypsin protease inhibitor (Pi) phenotypes in bloodstains. Neuraminidase elution of bloodstains, together with isoelectric focusing, immunofixation, and silver staining techniques, makes possible Pi subtyping in old bloodstains. No extra bands appear when the storage time is no longer than three months. 相似文献

Over the years, the prevailing correctional orientation in the United States has shifted back and forth between punishment
and rehabilitation. These changes in correctional ideology are typically marked by differing sentencing practices and changing
criminal justice research agendas. On the other hand, how corrections is legally mandated to operate is less understood. In
1993, Johnson, Dunaway, Burton, Marquait, and Cuvelier assessed the legally prescribed functions of community corrections
for all 50 states and classified them as either reform or control oriented functions. They concluded the majority of states
were primarily reform oriented. In this study, we replicate Johnson et al.’s (1993) methods using the statutes from all 50
states in 2002. However, we classified our findings, as well as recoded Johnson et al.’s (1993) findings, into punishment
or rehabilitation functions. We make comparisons between 1992 and 2002 for the purpose of assessing where legally mandated
orientation of community corrections stands today on the punishment/rehabilitation debate. 相似文献

In 1976 the author published the results of a study of antitrust class actions in the Northern District of Illinois. At the time the data for that study were collected a substantial portion of the cases included in the study were pending. In the present article the author reassesses the findings of his earlier study on the basis of newly collected data on the cases that were then pending. Among the issues discussed are the comparative burdensomeness of class and nonclass cases, the alleged in terrorem effect of the class action on antitrust defendants, and the results achieved through the use of the class action. 相似文献
